Weapons don't rust and enemies killed at checkpoints stay dead, but that's not what makes early September's Far Cry 3 so different from Far Cry 2.

Nah, what makes it different is that this year's Far Cry is about maybe losing your mind on a remote jungle island, where a brother and sister pull you in two very different directions, both of which appear to converge into a conflagration of sex and violence.

I played a demo of Far Cry 3 a couple of weeks ago and will have a lot more coverage about the game in the days to come. But for now, I must confess that the thing that lingers most vividly from that demo isn't that the game brings back the wild flame propagation gameplay of the last one nor that your character seems as lethal as he seems mad.

What lingers most is that the single-player demo I played began with a first-person view from our hero's eyes of a topless woman straddling him. You'll see it in the trailer below. The developer-narrated walkthrough skips it, but is just as not safe for work. More importantly, things get ever wilder from there.
